I have a LOW KM GS, which someone kindly drowned years ago, then 'hid' at the back of a workshop (and yes, that is actually what is in the log, 'found' parked in rear of workshop). Original motor had bent conrods (yes, I will rebuild it, different story).
Just bought a 4DB1T at auction, have the chart where gives details of its 2 hrs run in, and torque test, before being stored. Basically drop in ready, with a new clutch on it, and new throw out bearing in the box with it.
I am in the process of obtaining the power steering parts, and replacement brake master, clutch, and clutch slave (after sitting that long all suspect).
Would appreciate information from anyone else who has dropped one of these in, as to any issues that may arise.
I will unbolt the airconditioning compressor, until I can source the parts.
I have already decided to upgrade the radiator (North Qld summers are hot).[biggrin]

The engine already has a new, standard, turbo, Perentie, clutch. that should last a while, given the 4x4 is lighter than the 6x6, shouldn't it?
I have read others comments about clutch problems with Turbo, but looking at the testing charts supplied with the engine, at run in, it produced a max of 91.6 kw of power when tested, and 300Nm of torque; those are not earth shattering figures.
I was expecting a few years of out that clutch set up, before a required upgrade.

And I am lucky to have the gear to be able to lift the motor in and out, if I need to.

If you're happy with 91kw at the flywheel then I guess it will survive. All depends what you plan to do with the vehicle.
I have a 6x6 clutch in my county, I can make it slip.
Had a truck clutch in my Rangie, which made over 100kw at the wheels and 650nm, that never slipped

If it doesn't work out I will change it. Can't imagine they used these clutches in the Perentie 6x6 without recognising an issue; it may have a short service life. It will die, then be replaced.

As I said, if you're happy with the 91kw, then it will be fine. If you want to extract more power, then be prepared
